So, we have a “clock” which starts ticking the moment something dies.Obviously, this works only for things which were once living.There are two techniques for dating in archaeological sites: relative and absolute dating.

Edwardsville Mayor Hal Patton and Glen Carbon Mayor Robert Jackstadt presented 'state of the city/village' addresses, including updates on current economic development projects within their respective municipalities, and a recap of 2016 projects, permits and sales tax data.

When it comes to dating archaeological samples, several timescale problems arise.

For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).

In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.

Although relative dating can work well in certain areas, several problems arise.
